Well, if you're sure it's fuel get a gauge on the fuel rail and get an actual pressure reading. If pressure is good check on the grounds which bolt to the side of the intake plenum again; pull them and scrub them and the manifold where they mount with sandpaper or a wire brush.

Oh, sorry, when you asked which pins I thought you were asking about jumping the fuel pump... To check codes see here: http://www.cygnusx1.net/Supra/TechTi...ror_codes.aspx

Is the injector resistor pack on the driver's side wheel well plugged in? Test it for 12v+ at the black wire with the orange stripe with the ignition in the ON position.
